To all whom it may concern:

l 3e it known that I, EPHRAIM D. KLOTS, a c tizen of the United States, residing in the city, county, and State of New York, have invented certain new and useful Improvements in Apparatus for Generating Terpene Ozonjd Vapor; and I do hereby'declare the following to be a full, clear, and exact description of the invention, such as will enable others-skilled in the art to which it appertains to make and use the same.

This invention relates to apparatus for generating a medicinal vapor from a substance of the terpene group. such as pinene. The invention is directed to the provision of an improved form of apparatus of this character which is simple in construction,

which may be manufactured at low cost,

which is of lightweight and small bulk, which may be readily cleaned and kept in a V sanitary condition, and whichis well ada ted for household use involving operation o the apparatus by unskilled persons and requiring that the danger of in ury to the operator be completely eliminated.

In apparatus of this character as hereto- J fore constructed, it has been common to provide an ozonizer for generating ozone,

means for vaporizing the terpene and a mixing chamber in which the vapor of terpene and the ozone are IIllXed. Such an apparatus is elaborate, cumbersome,'expensive,and

both-.diflicult to operate and difiicult to keep clean, and its use has been greatly restricted for these reasons. The present invention involves the provision ofan apparatus of an improved construction such that all of the objectionable features which have characterized the apparatus heretofore employed, 1ncluding those pointed out above, are eliminated.

7 One of'the features of primary importance in an apparatus constructed in accordance with the present invention involves the com- APPARATUS FOR GENEBATIN G TERPENE OZONTD VAPOR.

point of use in any suitable 0r convenient manner. The placing of the ozonizer close to the receptacle for the terpene so that the ozone generated comes at once into direct contact with the liquid terpene is a feature of great importance. The construction is greatly simplified, the size, cost and number of parts in' the structure aregratlygreduced and the danger of the escape of free ozone is practically eliminated. Furthermore, the air which is forced through the ozonizer .with a moderate velocity sufficient tomaintain the necessary supply of air serves "to prevent undue heating of the ozonizing apparatus and at the same time the comparatively sllght elevation of the temperature in and about the" ozonizer serves to warm the terpene to the extent desirable for accomplishing the vaporization thereof freely.

The invention also involves the compact arrangement of the necessary parts of the apparatus so as to form a complete unit of relatively small dimensions which may be readily carried from place, to place, if desired, by hand. ,To this end a rectangular casing is providedhaving a vertical partition dividing it into two sections, one containing a.vapor generating apparatus and the other containlng the electrlcal. devices.

The electrical devices include a transformer for raising the voltage to that required inv the ozonizer and a rotary fan for maintain; inga current of air through the ozonizer. A small electric motor is preferably employed for'driving the fan and when the apparatus is to be connected in a direct current circuit, this. motor may be combined with a suitable rotary converter for converting the direct curre t into alternating current. Preferably a small rdtary' coiiverting machine of the type known as a dynamotor is provided for supplying alternating current to the transformer and the fan is secured upon the end of its shaft. The ozonizer is mounted within thepther compartment of the casing, preferably a vertical POSitlOIl, it being connected at itsnpper end to the conduit leading from the .fan and having the receptacle .for the liquid terpene -positioned under its lower end. Theseparts,

namely t e ozonizer and the receptacle for the' terpene, are preferably arranged within" an inner casing within-which the generation of the ozone and the vaporizing and ozoniza ing of the terpene take place, as in this way the escape of free ozone is prevented and the heat -developed as an incident to the generation of ozone may be readily regubetter understood by reference to the '85 .sembled for cleanin and then reassembled.

lated so as to guard against an excessive rise of temperature and at the same time utilize such heat as is developed to warm theterpene to the point at which it vaporizes readily.

Another feature ofthe invention involves the arrangement of the parts in such a way as to permit them to be readily detached for cleaning and then reassembled. To this end a receptacle is rovided for the terpene which may be rea ily moved into position and withdrawn therefrom. Also, the inner casing within which the ozonizer and the receptacle for terpene are mounted is so These and other eatures of the invention following description taken in connection with the accompanying drawings which illustrate the preferred embodiment of the I invention.

The outlet 14' roni the casing 12 of the. fan is connected to a conduit 15 which car- "ries air from the fan to the ozonizer. r In the rear compartment of the casing 7 and below the shelf 9 is a transformer having a primaryycoil 16 and secondar coils 17 The primary coil 16 ma be provi ed with a plurality of taps 18 as s own in Fig. 2 whichmay beutilized in selected pairs to obtain the volta e desired forvthecurrent. flowing in the circuit of the secondary coils 17. The electrical connections of the arts so far described are shown in Fig.2. The incoming wires 19 lead to the converter 10, a safety device 20 being inserted in one of the wires. From the, converter 10, wires 21-lead to a selected pair ofthe taps 18 of the primary coil 16 of the transformer, a safety device 20 being inserted in one of these wires 21 if desired. '.Wires 22 lead from the secondary 1 coils of the transfo rmer through openings in f the vertical pa'rtitlonv 8 to theozonizer.

Within the "compartment at the front of the casing is an inner casing or com artment withinwhich is 'the ozonizerand the receptacle forthe liquid terpene and wherein the terpene ozonid vapor is generated. This inner casing has a rear wall 25 and a side wall 26 rigidly mounted upon the central partition 8 ofthe mainicasing and it has a sidewall 27 and afront wall 28 which are connected by a hinge to the outer edge of the side wall 26. When these walls are in the positions shown in 4, they form an 1111161" compartment 0 rectangular crosssection. The coacting portions of the hinged and fixed walls are provided with vertical grooves forthe reception of gaskets. 29 so that when the inner compartment is closed, it is substantially air-tight. At the inner edge of the movable wall 27 are suitable latches 30 whereby the parts of the inner casing may be maintains in the closed position. This inner compartment is closed at 1-20 the lower end thereof by a bottom wall 31, one-half of which is of triangular form and secured to the walls 25 and 26 and the other half of which is 'of triangular form and secured to the walls .27 and 28. The n per 12-5 end of the inner compartment is simi arly closedby a top wall 32 one-half of which 'is of triangular shape and secured to the walls 25 and 26 and the other half of which is of triangular form and secured to the mug 27 opening is provided in this top wall 32.

The ozonizer is supported upon the top' wall 32 of the inner compartment and extends downward vertically to a point near the bottom of the compartment; The parts of the ozonizer are mounted upon a metallic tube 33 preferably made of aluminum. Its

size approximates the size of the circular I opening in the top wall 32 of the compartment and at its upper end is an integral flange 34 An annular gasket 35 formed of insulating material and consisting of two separable semi-circular pieces is mounted upon the two portidns of the top wall 32 and the flange34 of the tube33 is adapted to rest 0 the flange 341is. an annular gasket 36 of insulating material. The upper end of the preferably made of glass, having tube 33 is adapted to be closed by a disk 37, a central opening therethrough. This disk 3Tis held in position by means of a ring 38 having an internal flange 39. This ring is clamped in" position by means of screws 40' whose threaded ends enter openings in the flange Mend it serves to; hold the disk 37 .of glass in position.

The metallic tube 33 formsone electrode of a silent discharge, high tension electric ozonizer. The other electrode of the couple consists of a metallicfilm or coating 41 upon theinterior. surface of a glass cylinder or bottle '42, This bottle is mounted within the tube 33 with its cylindrical wall separated from the 'wall ofthe tube 33 by a. narrow space approximating one sixteenth of an inch. Preferably the cylinder 42 is'held in position concentric. with the tube" 33 by means of spacers 43 of non-oxidizable material at the upper and lower ends of the bottle, these elements 43 being spaced apart cirpassages for air between them.

cumferentiallyof the bottle so as to provide The bottle 42 is closed at its lower end,

as shown, and at its upper end it is provided 1 with a central opening of'substantial size.

A tube 44 of glass extends downwardly through the central opening in the disk 37 and through the opening in-the'upper end of the bottle 42 to a point close to the lowerclosed end of the bottle 42. It may be sustained in position by a clamp 45 gripping the tube 44 and bearing upon a gasket 46 which bears upon the glass disk 37.

At its u per end the tube 44 is bent laterally and 51 enters one end of a coupling 47 (Figs. 3 and 5). The other end of this coupling receives the end of the conduit 15 leading from the fan. Within the coupling is athrottle valve 48 mounted upon a shaft 49- which is IOtfim table in a fitting 50 secured to the under upon this gasket 35. On the upper surface e end of the horizontal portion wire 52 extends downwardlyto the end of the tube 44 concentric therewith and Itsv lower end is electrically connected to the metallic coating 41, preferably by having a plurality of chain links 53 connected to the lower end of the wire and resting by gravity upon the lower closed end of the bottle 42. The wire 52 is connected to one of the wires 22 shown in ,Fig. 2. The other of thetwo,

Wires 22 is connected to a binding post 54 mounted upon the stationary portion of the top32 of the inner compartment. This binding post 54 has a contact spring 55 secured thereto and projecting toward the tube 44.

so that when the parts are in the positions shown in Figs. 1 and 3, this spring arm 55 bears .upon the upper surface'of the ring 38 and thus makes electrical connection with the ring and the tube 33 to which it is secured.

Within the inner compartment and below the'lower end of the tube 33 is a space forthe reception of a receptacle 59 for the liquid terpene. 'This receptacle is preferably of rectangular form and fits snugl within the compartment but it may be rea ily withdrawn from the compartment when the latterhas been opened. The compartment is opened by releasing the latches 30 and turning the walls 27 and28 about their hinged connection to the ,wall 26, carrying The front wall 28 of the inner compartment preferably consists of a rectangular frame with a pane of glass set therein and the door- 24 of. the main casing may also have 1 a sheet of glass therein so that it is possible to see the parts within the inner compartment at all times. The vapor generated within the compartment rises therein and passes out through a tube 56. The lower end ofthis tube'fits tightly within-an opening in the stationary portion of the top 32 of the inner'compartment and the tube extends up wardly through an opening in the top of the' casing 7 .Fig. 6 shows a slight modification of the construction shown mFig. 1, wherein the lower end lot-the, tube 33 is threaded to receive a cap 57 to which a tube: 58 is connected; This construction may be employed when it is desired'to use a cldsed' receptaclcx-forthe; I I I I I v I 7 comes directlyiintocontact with. the; liquid 7 liquid terpene. and to convey the ozone from the ozonizer toithis receptacle, the receptacle being provided with a; separate outlet 'tube[ for the vapor generated therein. v

The ozone issuing from the lower end of the tube 33 comes into direct contact with the liquid terpene' in the rceptacle 59 and its contact therewith causes the 5 generation of terpene ozonid vapor. This vapor rises from the rece tacle 59 and moves withthe current upwardiy within the inner compartment and passes ouj; through the tube 56 in the form of a dense, light cloud. The current of air passing through the ozonizer by this tortuous routecarries ofl heat to such an extent'as to prevent the parts of the ozonizer from being raised to an objectionably ill-Eh temperature bg the heat developed by t e electric disc arge.

In orderto remove this 'receptacle itis only necessary to open the hinged doors of the main casing and the in Furthermore, the ozonizer should be cleaned from time to time in order that the. best results may be obtained and the apparatus is so constructed as to facilitate removal, disassemblage, cleaning and reassemblage of the ozonizer. When the doors of the outer casing and the inner comartment are opened, the entire ozonizer isr'ee to be drawn forward horizontally, breaking the airand electrical connections thereto. Then the inner tube and the glass bottle may be removed from the outer me tallic cylinder. 7

One of the'mos't important features of the apparatus is the provision of a chamber within which are both the ozone generatin I apparatus and the terpene and from which the terpene ozonid vapor issues. By reason of the provision of such a construction, the danger of the liberation of free. ozone is gracticall eliminated. The compartment oundei y'the walls 25; 26, 27 and 28 conelements of the ozonizer and as the 0 zonc issues from the ozonizer it comes ene which at once into contact with the ozone in the tray 59 also located 7 within the compartment. The chemical reaction between terpene and ozone takesplace practically. in

stantaneously, Therefore, the ozone issuing from the ozonizer tube directly upon the and can be removed, cleaned and, restoredas desired. 4

Fi 7 illustratesa modified construction whic may be employed .in lieu of that .shown in the other figures. The characteristic feature of this modified construction is the same as that of the construction shown in Fig. 1, namely that the ozonizer and the mate rlal to be ozonized are both located within the same. inclosure so that ozone issuing from the ozonizer-comes in direct contact with the material from which the o'zonid vapor is to be formed, and that this inclosure maybe readily removed, so. "as to ermit of the necessary cleaning. In Fig. ,theinclosure consists-of a glass jar closed at its lower end and the bottom portion of this jar constitutes the receptacle for the liquid terpene and t 'e ozonizer'is adapted to be mounted within the upper portion of the jar. This construction is more .simple and more economical than that shown in Fig.- 1 and the arts of the receptacle can be-more readily ept clean.

Referrin to the Fig. 7 construction more in detail, t 0 jar constituting the inclosure for the ozonizer and the terpene is shown at 70.- It is preferablymade of glass and is closed at its lower end. The upper end of the inclosure or jar is flanged, as indi- .cated at 71. This jar is adapted to beseated within a circular wall 72 located upon the bottom of the casing and it is held from lateral'movement by means of spring arms 73 which partially embrace the jar. The ozonizer shown in Fig. 7 is similar .in con-' struction to that illustrated in the preceding figures and itis sustained .in position by a cover 74 for the jar 70. This cover is made of an insulating material, it circular 1n form and it is provided with'an open-- ing through which the ozonizer extends,the

flange at the top of the'oz'onizer restin upon the. upper surface of the cover 74.' gasket 75 is preferably placed between the cover 74 and ange 71. vapor outlet tube is shown at 76 projecting through an open- 66 ing in the casing of the apparatus and also through an opening provided in the cover 74. Preferably, the position of the ozonizer is slightly eccentric to the jar to ncre se the space on one side for the tube 76. Be-- "cause of this, pins7 7 are preferably provided' in the cover 74 in position to enter 7 openings provided for their reception 1n the flange 71 of the jar 70. By reason of the provision of these pins and openings, the jar and 'cover, must necessarily be brought to theappropriate positions when assembling the parts.

With this'Fig. 7 construction,-the bottom of the jar 70 is employed as the receptacle for the liquid terpene and the ozone issuingfrom the lower end of the outer ozonizer tube 33 comes into direct contact with the liquid terpene below the ozonizer. The .vapor formed as a result of this contact'of ozone and terpene rises within the jar and passes out through the outlet tube 76.

It will be seen that, as in the Fig. 1 com I struction, the ozonizer and the liquid terpene are inclosed within a single chamber,

so that escape of free ozone is eflectually guarded against. In order to clean the parts or to renew the supply of the liquid terpene, the outlet tube 76 is first withdrawn from the opening in the cover 76 and then r the jar 70 is raised slightly soas to free it from the positioning flange 7 2." Then the entlre jar 70 and the parts mounted thereon are moved forwardly and the air tube '44 is withdrawn from the coupling 47. There-- after, the entire ozonizer may be drawn up. out of thevopening in the cover 74 and the latter removed from the jar. 71 so that all of the'partsmay be readily cleaned and a new supply of the terpene placed in the bottom of the jar 70.

While I have illustratedianddescribed herein the construction which I believe to be best adapted for use in practising my invention, I'wishit understood that the invention is not limited to features of construction, as these may be varied between wide limits. Many of the parts of the ozonizer may be made of moldable insulating material such as bakelite; this is particularly true of the cover for the ozonizer chamber. Also, the outer electrode 33. of the ozonizer may 0011-.

sist of a tube of bakelite with an. aluminum tube inserted therein. By employing such a construction, an economy in manufacture is attained, as then the aluminum tube may be a piece cut from a length of tubing and may not require a special machine. Furthermore,

I have described the inner electrode as conslstlng of'a glass cylinder having a metalcoatln applied to its inner surfacein any suitabe manner, as by flowing it thereon or electrofdepositing it thereon; instead, however, the metal coating of the inner electrode maybe a cylindrical sheet removably applied to the interior surface of the glass latter 'construction there 'is less danger of" breaking dwn.the insulation betweenthe cylinder of the inner electrode. -With this two electrodes and the cost of maintaining the apparatus at this high efiiciency is therefore substantially reduced.
